Geometracal Structures of Fundamental Color Space

摘要：

Human Color Vision is characterized by metamerism. J. B. Cohen interpreted metamerism by a projector called matrix R onto HVSS (Human Visual Sub-Space) and founded FCS (Fundamental Color Space) spanned by a matrix F with a selected triplet of column vectors in R. This paper presents a new FCS created by a different from the choice of matrix F. First, a pseudo-inverse projector P<,INV> from XYZ to fundamental metamer is introduced. Next, the base functions of P<,INV> are transformed to an orthogonal matrix F by Gram Schmidt method. This matrix F proves to be an orthonormal linear transformation of xyz color matching function and spans a new FCS. The paper discusses the geometrical structure of FCS in relation to matrix F and introduces its application to the spectral design of color input devices.
